I am trying to mark points and form a loop around the face in front. Then I rotate my object to get another face as front face and try to enclose it in a loop. Problem is : When I successfully form the first loop and then rotate the object, the loop disappears. Secondly, I am unable to form 2 loops at a time that are disjoint. Here is code section I am trying to play with :

  if(bFlag_LineDraw) //removed temp
	  {
		   
		 
		   //while(piClickTracker[k])
		   {
			   
               
			   glMatrixMode(GL_MODELVIEW);   
		       
			   
			   glPushMatrix();
			   glLoadIdentity();
			   glRotatef(fAngle_Y , 0.0 , 1.0 , 0.0);  //Move left 
			   glRotatef(fAngle_X , 1.0 , 0.0 , 0.0);  //Move above 
			   glRotatef(fAngle_Z , 0.0 , 0.0 , 1.0);  //Move above   
			   
			   if(!(k % TWO))
					glColor3f(1.0 , 0.0 , 0.0);              
               else
					glColor3f(0.0 , 00 , 1.0);              
		   
			   
			   while(piClickTracker[k])
			   {
                 
				 glBegin(GL_LINE_LOOP); 
				   //glBegin(GL_LINES);
				   while(j < piClickTracker[k]) 
				   {  
					 .
					  glVertex3f(SHIFT_COORD_SIGN * pfArray,  pfArray, pfArray ); //Modified ..temp
					  i += 3;
					  j++;				  		  
				   }

				   j = 0;
				   iTemp += 1;
				   ++k;			   
				  glEnd();
		          glPopMatrix(); 
			   }//Outer While Ending.
		    	
		    //glPopMatrix();
		      
		   }

         bFlag_LineDraw = FALSE;
		 
	  }
